CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 257,923, dated May 16, 1882.

Application filed October 24, 1881. (No model.)

.hereby declare that the following is a full,

clear, and exact description of`the invention, which will enable others skilled in the art to which it appertains to make'and use the same, reference beinghad to the accompanyingdrawings, which form a partof this specifica-tion,

and in which- Fignre l is a longitudinal vertical sectional view of my improved car-coupling. Fig. 2 is a perspective view of the couplinglink. Fig. 3 is a horizontal sectional view of the same. Fig. 4 is a side View, showing a modied construction of the link. Fig. 5 is a view of the coupling-pin.

Corresponding parts in the several figures are denoted by like letters ofreference.

This invention relates to automatic or selfacting car-couplings; and it consists in certain improvements in the construction of the same, which will be hereinafter fully described, and particularly pointed ont in the claim.

In the drawings hereto annexed, A represents the body of the car. B is thebuinperor draw-head, which is provided in the usual manner with a horizontal mouth orrecess, B', and a vertical pin-hole, O.

D is the coupling-link, which consists of a at plate, E, provided atthe ends with horizontal recesses F, in each of which a pair of arms, G G,.are pivoted upon vertical pins or pivots H, so as to swing in ahorizontal plane. The arms G are provided with recesses I upon their inner sides, adjoining each other, and .coiled springs J are placed in the said re-` cesses and secured at their inner ends by vertical pins K, or in any other suitable manner,

so as to drawthe said arms toward eachother,

readily between the arms of the coupling-link and tit readily in. the opening provided for its accommodation- This construction also prevents accidental uncoupling, which might hap pen if the pin were of the usual cylindrical shape. At its upper end thepinNis provided with a flange, O, resting on top of the drawhead, and from the said flange a stem,]?, projects in au upward direction, having its bearing in a bracket, Q, projecting from the end of the car. The upper end of the stem P is connected in any suitable manner to a lever, R, arranged at the top or upon the platform ot' the car for convenience in uncoupling, and a spring, S, is coiled upon the stem, between the bracket Qand the head or flange O of the pin, for the purpose of forcing the latter in n. downward direction.

From the foregoing description, taken in connection with the drawings hereto annexed, the opera-tion of my invention Will be readily understood. When the cars come together the link which has been previously adjusted in one draw-head enters the draw-head of the opposite car, thus striking the pin N which separates the arms G G and enters the opening provided for its reception. Uncoupling may be readily effected by means of the le ver R.

In Fig. et of the drawings I have shown a modified constructionl ot' the coupling-link, which consists in simply arranging the arms G at opposite ends ot' the plate E at various heights, thus adapting the link for coupling cars of a different height.

Having thus described my invention,I claim and desire to secure by Letters Patent of the -United States- Y.

As an improvement in coupling-links, the

plate E, having recessesF Fand pivoted arms G G G G, provided with beveled ends M, notches L, and recesses I, to receive the springs J, which are held in said recesses by vertical pins K, substantially `as set forth.

In testimony that I claim the. foregoing as myown l have hereunto affixed my signature in presence of two witnesses.
